Description
Technical Field
[0001] The utility model relates to the field of test tubes, in particular to a test tube for bacterial culture. Background Art
[0002] Bacteria culture test tubes are usually made of high-quality borosilicate glass or high-temperature resistant plastic to ensure good chemical stability and transparency during high-temperature sterilization and cultivation. Suitable culture media, such as agar plates, liquid culture media, etc., can be loaded inside the test tubes to provide the necessary nutrients for microbial growth. Before cultivation, the test tubes and their contents must undergo strict sterilization treatment, such as wet heat high-pressure sterilization, to eliminate all bacteria and ensure the accuracy and repeatability of the experimental results. Bacteria culture test tubes are widely used in scientific research, medical diagnosis, industrial fermentation, and teaching.
[0003] Existing test tubes for bacterial culture provide a relatively closed environment, which can effectively maintain the internal sterile state when used in conjunction with sterilization technology, which is crucial for the pure culture of microorganisms. However, during the experiment, the operator holds a rubber-tipped dropper or other test products in one hand, and most of the time needs to take the test tube with one hand. Since the test tube cover and the test tube are separate, the test tube cover is particularly easy to fall off, affecting the operator's experiment and reducing the convenience of using the test tube for bacterial culture. Therefore, it is urgently necessary to design a test tube for bacterial culture that can prevent the test tube cover from falling off. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a test tube for bacterial culture, so as to solve the technical problem that the test tube cover of the test tube for bacterial culture is easy to fall off.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a test tube for bacterial culture, comprising a test tube body, a test tube cover is arranged on the top of the test tube body, a connecting block is arranged on one side of the bottom of the test tube cover, and the bottom end of the connecting block is rotatably connected to a push-pull ring through a rotating shaft.
[0006] By adopting the above technical solution, when it is necessary to use a test tube to culture bacteria, the operator can separate the test tube cover from the test tube mouth on the test tube body by rotating the test tube cover. The push-pull ring and the connecting block rotate synchronously to ensure smooth operation. At the same time, after the test tube cover is completely separated from the test tube body, the push-pull ring is cleverly stuck on the test tube body due to the threaded design of the test tube mouth, which effectively prevents the test tube cover from falling off accidentally. Subsequently, the connecting block rotates through the rotating shaft to drive the test tube cover to one side of the test tube body, thereby completely avoiding the problem of the test tube cover falling off due to careless operation.
[0007] Furthermore, the test tube cover and the push-pull ring are coaxially arranged, and the test tube cover, the connecting block and the push-pull ring rotate synchronously.
[0008] By adopting the above technical solution, the coaxial setting ensures the stability of the test tube cover and the push-pull ring during the rotation process, and prevents shaking or deviation caused by different axes.
[0009] Furthermore, a test tube opening is provided on the top of the test tube body, and the test tube opening is threadedly connected to the test tube cover via a thread groove.
[0010] By adopting the above technical solution, the threaded connection method can ensure that the test tube cover tightly and firmly closes the test tube mouth, effectively preventing the invasion of gas and microorganisms, which is crucial for maintaining a sterile environment inside the test tube.
[0011] Furthermore, the lower outer side of the push-pull ring is provided with an inclined structure to provide a push-pull point for the operator.
[0012] By adopting the above technical solution, the inclined structure provides the operator with a clear push and pull area, which is convenient for hand positioning and operation, making opening and closing the test tube cover easier and more intuitive.
[0013] Furthermore, a silicone anti-skid layer is provided on the surface of the push-pull ring to increase the friction coefficient between the test tube body and the operator's hand.
[0014] By adopting the above technical solution, the silicone anti-slip layer can significantly increase the friction coefficient between the push-pull ring and the operator's hand, so that the hand can grasp the push-pull ring more firmly when operating the test tube, reducing the possibility of hand slipping.
[0015] Furthermore, the push-pull ring and the connecting block are both made of polycarbonate, which has good resistance to chemicals.
[0016] By adopting the above technical solutions, polycarbonate, as a strong thermoplastic, has good resistance to a variety of chemicals, which means that in a laboratory environment, the push-pull ring and connecting block can withstand the corrosion and erosion of common chemicals and maintain their structural and functional integrity.
[0017] In summary, the utility model mainly has the following beneficial effects:
[0018] 1. The utility model uses a push-pull ring. When a test tube is needed to culture bacteria, first, the test tube cover is rotated to separate it from the thread of the test tube mouth on the test tube body. At the same time, during the separation process, the push-pull ring and the connecting block rotate synchronously to ensure the continuity and stability of the operation. When the test tube cover and the test tube body are completely separated, the push-pull ring is cleverly stuck on the test tube body due to the thread of the test tube mouth, effectively preventing the test tube cover from accidentally falling off. Subsequently, the connecting block rotates through the rotating shaft to safely turn the test tube cover to the side of the test tube body, thereby solving the problem that the test tube cover may fall due to instability, which not only improves the convenience of the bacterial culture operation process, but also ensures the safety and stability of the experimental process;
[0019] 2. The utility model provides a push-pull ring, and the silicone anti-slip layer on the push-pull ring is made of a fine material and has a certain viscosity. This characteristic enables it to effectively enhance the friction between the operator's hands when they come into contact with the operator's hands, and to a certain extent reduce the sliding of the hands due to sweat or a wet environment. Therefore, the silicone anti-slip layer plays a key role in improving the friction between the operator's hands and the push-pull ring, thereby ensuring stability and accuracy during the experimental operation.

For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.
[0028] The following describes an embodiment of the utility model based on its overall structure.
[0029] A test tube for bacterial culture, such as Figure 1-Figure 4 As shown, it includes a test tube body 1, a test tube cover 2 is arranged on the top of the test tube body 1, and a connecting block 3 is arranged on one side of the bottom of the test tube cover 2. The bottom end of the connecting block 3 is rotatably connected to a push-pull ring 4 through a rotating shaft 5. When the test tube needs to be used to culture bacteria, the operator can separate it from the test tube mouth 6 on the test tube body 1 by rotating the test tube cover 2. The push-pull ring 4 rotates synchronously with the connecting block 3 to ensure the smoothness of the operation. At the same time, after the test tube cover 2 is completely separated from the test tube body 1, the push-pull ring 4 is cleverly stuck on the test tube body 1 due to the threaded design of the test tube mouth 6, which effectively prevents the test tube cover 2 from accidentally falling off. Subsequently, the connecting block 3 rotates through the rotating shaft 5 to drive the test tube cover 2 to rotate to one side of the test tube body 1, thereby completely avoiding the problem of the test tube cover 2 falling off due to careless operation, and effectively ensuring the safety of the experimental process and the maintenance of the sterile operating environment.
[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 4The test tube cover 2 and the push-pull ring 4 are coaxially arranged, and the test tube cover 2, the connecting block 3 and the push-pull ring 4 rotate synchronously. The coaxial arrangement ensures the stability of the test tube cover 2 and the push-pull ring 4 during the rotation process, and prevents shaking or deviation caused by different axes. At the same time, the synchronous rotation design of the test tube cover 2, the connecting block 3 and the push-pull ring 4 enables the operator to rotate other components smoothly when rotating the test tube cover 2, thereby improving the fluency and efficiency of the operation, which not only simplifies the operation steps, but also reduces the difficulty of operation, thereby improving the convenience and comfort of the experimental process.
[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A test tube mouth 6 is provided at the top of the test tube body 1, and the test tube mouth 6 is threadedly connected to the test tube cover 2 through a threaded groove. The threaded connection method can ensure that the test tube cover 2 tightly and firmly closes the test tube mouth 6, effectively preventing the invasion of gas and microorganisms, which is crucial for maintaining the sterile environment inside the test tube. At the same time, the threaded connection also makes it easy for operators to open and close the test tube, improving the convenience of experimental operation. In addition, this connection method also has good durability and can withstand repeated opening and closing operations, ensuring the stability and reliability of the test tube in long-term use.
[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The lower outer side of the push-pull ring 4 is provided with an inclined structure to provide a push-pull point for the operator. The inclined structure provides the operator with a clear push-pull area, which is convenient for hand positioning and operation, making opening and closing the test tube cover 2 easier and more intuitive. At the same time, the inclined structure can also increase the contact area between the hand and the push-pull ring, provide better mechanical support, and reduce possible slippage or misoperation during operation, thereby improving the stability and safety of experimental operations, which not only optimizes the user experience, but also improves the experimental efficiency.
[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The surface of the push-pull ring 4 is provided with a silicone anti-skid layer for increasing the friction coefficient between the test tube body 1 and the operator's hand. The silicone anti-skid layer can significantly increase the friction coefficient between the push-pull ring 4 and the operator's hand, so that the hand can grasp the push-pull ring more firmly when operating the test tube, reducing the possibility of hand slippage. At the same time, the increased friction coefficient also improves the stability and control of the operation, so that the operator can control the test tube more accurately, which is particularly important when performing delicate experimental operations. It not only improves the safety of the experimental operation, but also ensures the accuracy and reliability of the experiment.
[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The push-pull ring 4 and the connecting block 3 are made of polycarbonate, which has good resistance to chemicals. As a strong thermoplastic, polycarbonate has good resistance to a variety of chemicals, which means that in a laboratory environment, the push-pull ring 4 and the connecting block 3 can withstand the corrosion and erosion of common chemicals and maintain the integrity of their structure and function. At the same time, the durability of polycarbonate also ensures that the push-pull ring 4 and the connecting block 3 can withstand long-term use and repeated disinfection, reducing the frequency of loss and replacement, thereby improving the economy and sustainability of the test tube. This material selection not only improves the practicability of the test tube, but also ensures the safety and stability of the experimental process.
[0035] The implementation principle of the utility model is as follows: when it is necessary to use a test tube to culture bacteria, the test tube cover 2 is first separated from the test tube mouth 6 on the test tube body 1 by rotating the threads, and the push-pull ring 4 and the connecting block 3 rotate synchronously. When the test tube cover 2 and the test tube body 1 are completely separated, the push-pull ring 4 is stuck on the test tube body 1 due to the threads of the test tube mouth 6, and then the connecting block 3 rotates through the rotating shaft 5, causing the test tube cover 2 to rotate to one side of the test tube body 1, so that the test tube cover 2 will not fall due to not being held firmly.
[0036] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
